What is the universal energy currency of cells?

ATP

100

What is creatine kinase?

The enzyme that catalyzes the breakdown of creatine phosphate to produce ATP.

100

The first 30 seconds of exercise
emphasizes _______?

What is ATP-PC

100

Hydrogen Atoms contain one ______ and one _____?

What is proton and electron 

200

What is NAD+?

Regenerates the coenzyme for glycolysis to continue under anaerobic conditions

200

What is the end product of glycolysis while in an anaerobic state?

lactic acid

200

what is the primary source of
energy at rest and during extended, low-
intensity activities.


What is Aerobic Metabolism

200

Oxidation is ______ an electron 

Reduction is ______  an electron

what is removing and addition

300

What is creatine phosphate?

Primary energy source molecule that is hydrolyzed for quick energy for quicker reaction time during muscle contraction. (ex. sprint)

300

What is a redox reaction?

This reaction involves the transfer of electrons from one molecule to another.

300

Function of the Krebbs cycle 

what is Oxidize substrates 

300

The process by which triglycerides are broken down into glycerol and free fatty acids

What is lipolysis?

400

What is anaerobic threshold?

Metabolic state occurs when oxygen is unavailable, and the energy that is required exceeds aerobic capacity.

400

What is the phosphagen (ATP-PCr) system?

This energy system is predominant during the first 10 seconds of high-intensity activity.

400

What does cause muscle soreness?

Microscopic injury to muscle fibers

400

what is Oxygen debt?

what is oxygen taken in above
resting values after exercise


500

What are hydrogen ions and how do they affect muscle?

During anaerobic exercise, this ion accumulates in the muscle, leading to muscle fatigue.

500

What is excess post-exercise oxygen consumption (EPOC)?

This measure represents the total energy expenditure above resting levels post-exercise and is linked to oxygen consumption.

500

RMR is a abbreviated term for ___?

Resting metabolic rate

500

This threshold marks the exercise intensity at which blood lactic acid levels begin to rise significantly above resting concentrations.

What is the lactate threshold?
